React-admin ra-data-graphql-simple пример и json-graphql-server

Это сработало с примером -

import buildGraphQLProvider from 'ra-data-graphql-simple';
import { Admin, Resource, Delete } from 'react-admin';
import { PostCreate, PostEdit, PostList } from './posts';

class App extends Component {
    constructor() {
        super();
        this.state = { dataProvider: null };
    }

    componentDidMount() {
        buildGraphQLProvider({ clientOptions: { uri: 'http://localhost:3000' }})
            .then(dataProvider => this.setState({ dataProvider }));
    }

    render() {
        const { dataProvider } = this.state;

        if (!dataProvider) {
            return <div>Loading</div>;
        }

        return (
            <Admin dataProvider = {dataProvider}>
                <Resource name = "Post" list = {PostList} edit = {PostEdit} create = {PostCreate} remove = {Delete} />
            </Admin>
        );
    }
}

export default App;
